对……来说 means "for someone, from someone's point of view". It says a judgement holds for a particular person: 对我来说,这个工作很合适 (for me, this job is a good fit).
It almost always comes at the start of the sentence, followed by a comma.
Don't confuse it with plain 对 (towards: 他对我很好) or with 我觉得: 对我来说 highlights the person's situation, 我觉得 states an opinion.
